Abstract: In this paper we present our practical experience in benchmarking a number of existing Web Services, and investigating the instability of their performance and the delays induced by the communication medium. We provide the results of statistical data analysis and discuss a technique of Web Services performance assessment taking out of the network delays. We have found that the uncertainty discovered in Web Services operations affects dependability of Service-Oriented Architecture and will require additional specific resilience techniques.
